Hi Benoît, I don't know - but I do find this in their email headers:
X-Bluewin-Spam: Cloudmark
-> https://www.cloudmark.com At the bottom of that page you can even find the Swisscom logo. My 2 cents, hope they help! Gruass, Franco On 10/31/17 15:08, Benoit Panizzon wrote:
Hello List A Mailserver from a business customer of ours is blacklisted @ bluewin. The Error Message from Bluewin MXes directing to the removal site: https://www.swisscom.ch/en/res/hilfe/ip-blacklist.html Our customer has requested removal via this form, no success. Our customer has contacted bluewin and opened a trouble ticket. He got the information that his ISP (us) should take care to remove his IP from the blacklists, but is not getting any information about which blacklists. http://multirbl.valli.org Blacklisted: 0 We are at a loss. Does anyone know what kind of blacklists bluewin uses? Kind regards -Benoît Panizzon-
